the production of microbial metabolites and biomass
(Chanda et al., 1984). The effect of the ethanol:glucose
ratio in the medium on the fermentation
activity and the composition of baker's yeast was
studied by Kylova and Eroshin (1991). The vitamins,
biotin, pantothenic acid and inositol are essential for
optimum growth of S. cerevisiae (White, 1954). The
vitamin content of yeast was discussed by Seeley
(1951), Kirchoff (1960) and Gyorgy (1954).
